Is this right;
b is correct. for a it's asking where its undefined. meaning when does the denominator equal zero. so factor x^2+3x-10, and set the value to zero to solve.
oh it is (x-5)(x-2)
(x+5)(x-2) now solve individually
your answer is right, @malibugranprix2000 . One vertical asymptote and one discontinuity, and no horizontal asymptote. i'll assume that you have solution to your answers.
oh btw the bottom one is hidden it is what is the oblique asymptote? I believe the answer is -5
for that question you're gonna have to do polynomial division or synthetic division
I meant for the first one is -5 right?
the oblique asymptote is the line y = x-3. Divide the numerator by the denominator by long division, the quotient is your "oblique" asymptote
x=-5,2 are the vertical asy. x-2=0 is 2
\[\large \frac{ x^3-8 }{ x^2+3x-10 }=(x-3)+\frac{ 19 }{ x+5 }, x \neq 2\]
i assumed he hasn't learned discontinuity yet. but yea x=5 would be it
x=2 is not a vertical asymptote, since \[\frac{ x^3-8 }{ x^2+3x-10 }=\frac{ (x-2)(x^2+2x+4) }{ (x-2)(x+5) }=\frac{ x^2+2x+4 }{ x+5 };x \neq 2\]
Yea x=2 gets cancled right?
yes
oh ok so its not -5 its 5?
that was a mistake when i posted the reply i forgot to put in the neg. sign on 5
oh ok no problem. thanks for the help @technofable and @sirm3d
